The Indian government must not use “equity” to block climate change negotiations. It must be proactive on equity and put forward a position on how to operationalise the sharing of the carbon budget—accounting for countries’ contribution to past emissions and allocating future space—in climate talks.

I wrote this last year when the UPA government was in power. I am repeating this as the NDA government prepares for the next conference of parties (CoP) to be held in December in Peru.

If you know that a sector has arrived when it makes for trade wars between countries, then solar energy clearly has. Last year, the US imposed anti-dumping duties on Chinese imports of solar panels; now the EU has proposed the same. The Chinese have in turn threatened that they will take action against European exports of poly-silicon, the material used for manufacturing solar panels. In February this year, the US filed a case against India at the World Trade Organization (WTO) for “favouring sourcing of panels from domestic manufacturers”.

India’s solar power policy is now entering round two. And there is much that needs to be reviewed and reworked as the business of solar energy has seen massive turbulence in India as well as globally. In the first phase (2010 to 2013) of the Jawaharlal Nehru National Solar Mission (JNNSM) the target was to set up 1,000-2,000 MW of grid-based solar power in the country. By 2013, the country has indeed commissioned some 1,000 MW of solar power, but 700 MW of this target comes from the non-JNNSM state of Gujarat.
